Product Name/Model:EB-SOC60G FCC ID:WR925SC1AG0ARC ReferenceFCC KDB 447498 D04 v01 FCC RF Exposure Where the Device Under Test (DUT) can be shown to meet the requirements for an exemption pursuant to FCC 47 CFR §1.1307(b)(3), an evaluation is not required with respect to the limits on human exposure to RF emissions provided in FCC 47 CFR §1.1310. 1.Determination of Exemption As per 47 CFR §1.1307(b)(3), for single RF sources (i.e., any single fixed RF source, mobile device, or portable device), a single RF source is exempt if: A.1-mW Test Exemption: The available maximum time-averaged power is no more than 1 mW, regardless of separation distance. This exemption may not be used in conjunction with other exemption criteria other than those in paragraph (b)(3)(ii)(A) of this section. Medical implant devices may only use this exemption and that in paragraph (b)(3)(ii)(A); B.SAR-Based Exemption: The available maximum time-averaged power or effective radiated power (ERP), whichever is greater, is less than or equal to the threshold P th (mW) described in the following formula. This method shall only be used at separation distances (cm) from 0.5 centimeters to 40 centimeters and at frequencies from 0.3 GHz to 6 GHz (inclusive). P th is given by: ( ) = ( 20 ⁄ ) ≤20 20 < ≤40 Where = − 60 And ( ) = 2040 0.3 ≤ <1.5 3060 1.5 ≤ ≤6 d = the minimum separation distance (cm) in any direction from any part of the device antenna(s) or radiating structure(s) to the body of the device user.

Page 2 of 5 C.MPE-Based Exemption: Using Table 1 and the minimum separation distance (R in meters) from the body of a nearby person for the frequency (f in MHz) at which the source operates, the ERP (watts) is no more than the calculated value prescribed for that frequency. For the exemption in Table 1 to apply, R must be at least λ/2π, where λ is the free-space operating wavelength in meters. If the ERP of a single RF source is not easily obtained, then the available maximum time- averaged power may be used in lieu of ERP if the physical dimensions of the radiating structure(s) do not exceed the electrical length of λ/4 or if the antenna gain is less than that of a half-wave dipole (1.64 linear value).

The EUT contains 57.0 – 64.0 GHz transmitter. EIRP exemption threshold was calculated using the lowest operating frequency for each transmitter; the lower frequency resulted in a lower exemption limit. ERP exemption threshold was calculated using the lowest operating frequency for each transmitter; the lower frequency resulted in a lower exemption limit. 2.1DUT RF Output Power Highest power (peak or average) for each operation band was used in the RF exposure evaluation.

And the transmitter operates below its applicable Threshold ERP Limit; thus, the RF Exposure Exemption requirement is met. According to 47 CFR §1.1307(b)(3)(i)(B), this device complies with the RF exposure test exemption. 3.Host RF Exposure Evaluation The host is a mobile device designed to be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the RF source's radiating structure and the body of the user or nearby persons. ERP exemption threshold was calculated using the lowest operating frequency for each transmitter; the lower frequency resulted in a lower exemption limit. 3.1Host Transmitter RF Output Power The host contains 902 – 928 MHz FHSS/Hybrid transmitters, 2400 – 2483.5 MHz DTS/FHSS transmitters, 5.2 GHz and 5.8 GHz WLAN transmitters.
